For decades, one of the most famous scientists of our time has been making society think about the fundamental laws of nature and the inextricable connection between science and society. In his new book, The Still Unknown Universe, Steven Weinberg covers a wide range of topics: from cosmological problems to social ones, from astronomy, quantum mechanics and scientific theory to the limitations of modern knowledge, the art of scientific discovery and the benefits of mistakes. Nobel Prize winner Steven Weinberg shares his views on fascinating fundamental questions in physics and the structure of the Universe. At the same time, he manages not to be limited by narrow disciplinary boundaries and not to hide from political topics, including the inexpediency of manned space flights, problems of social inequality and the importance of supporting big science.
